How To Build The Ultimate Small-Form-Factor Gaming PC
Torture Testing the Wee PC
So, how does our new Mini-ITX rig stand up to the Maximum PC Lab’s zero-point configuration? Not well, at first blush. The wee PC ran 44 percent lower frame rates in the gaming benchmarks, and 17–24 percent slower everywhere else.
Hardly stellar, but a quick glance at last month’s $1,400 gaming machine build (“Builder’s Creed”) buoyed my spirits, at least where gaming is concerned. As we pointed out then, our zero-point machine is designed to go toe-to-toe with $7,500 multi-GPU gaming rigs, not budget builds. Plus, that box has the advantage of using a standard ATX motherboard, with plenty of room for expansion—something we eschewed in favor of smallitude.

Our small formfactor PC is svelte and powerful.
This mini-rig is indeed svelte: It’s just 7.5 inches tall, 8.65 inches wide, and 13.75 inches deep. You could stack three of ’em on top of each other and still take up less room than most of the systems we test in the Lab. And considering that the motherboard only has one PCI-E slot and two DDR3 channels, we think it holds up damn well. Just look at last month’s Acer Predator—that multi-GPU machine is less than 10 percent faster than my mini-rig, and it’s 20 percent more expensive, twice the size, and three times as ugly (in my opinion).
Alternate Configurations
Is my configuration the only possible one? Of course not. You could cut $300 by skipping the SSD, or go the other direction and add an aftermarket cooler and experiment with overclocking, opt for a different GPU or more RAM, or even add Blu-ray playback. And although I used the area between the GPU and the front of the case for cable storage, there’s plenty of room for longer GPUs, as long as they don’t consume too much power—our 600W power supply can’t handle a 5970, for example.
Finally, it’s worth noting that there are a few other Mini-ITX gaming boards out there. I happen to like the Zotac board used in this build because of its onboard Wi-Fi and plethora of USB and SATA ports, but Gigabyte’s GA-H55N, which adds USB 3.0—albeit at the expense of Wi-Fi and some of the other ports—is another option. Both boards feature full PCI-E x16 slots and the Gigabyte’s layout allows for a few more aftermarket cooler options.
The goal of this build was to prove to myself that a hand-built Mini-ITX gaming rig (as opposed to a more-expensive boutique SFF rig) was a probable—even reasonable—option. I believe I’ve done that, by building a $1,650 machine that performs well for the price, and is compact, quiet, and good-looking to boot.
